Multibank is suspected of tampering with data

Because I make short-term trading, my work will include recording the data of the highest and lowest price changes of K-line opening and closing every hour, every 4 hours, every day, and every week, and use this data to calculate and judge and deduce the trading model and find my trading point. I am very sensitive to data changes because it is being recorded in real time. Recently, when I needed to review the data changes in the first few hours, I found that the data was inconsistent. I thought it was a wrong copy, but it turned out that the data was slightly tampered, mainly because the third decimal place after the hourly point of the dollar against the yen has changed. I suspect that Multibank is tampered with transaction data! This creates artificial barriers to transactions. Investors are advised to be careful
